Zap2it reported it first
back in February when Marini told us and ABC confirmed that he was in negotiations to become a series regular.

Back then, the deal hinged on whether the series would be renewed (but, duh, we knew it would be).

"This is really cool," Marini told Zap2it in
an exclusive interview. "Doing something on TV with a massively amazing cast like that, I appreciate it. And being asked back, it's to die for."

Marini's promotion does come with some bad news. The TV gods giveth and they taketh away. We already knew Rob Lowe was abandoning ship, but we'll be losing another half-Walker. An ABC spokesperson confirms to Zap2it that Luke Grimes who plays Ryan, the mischievous half-brother, won't be returning to the show.

But, let's focus on the good news. When Gilles was still in negotiations to become a regular, he told us, "That would be my first regular TV part I've ever had, so it's very exciting. It's a huge accomplishment for me."
